LATQE FOB SLIDING DOORS.

Application filed February 15, 1927. Serial No. 168,404.

This invention relates to locks and latches and particularly to latches for sliding doors.

The general object of the invention is to provide a latch of an extremely simple char acter, which may be readily applied and which will hold a door closed until the door is manually released.

Another object is to provide a device of this character which may be applied and will operate in connection with a door which slides in either direction to a closed position and to provide a latch which may be opened either from the outside or inside.

My invention is illustrated in the accompanying drawings wherein 1 Figure l'is a horizontal section of the rear margin of a door and corresponding door jamb with my latch applied;

Fig. 2 is a face view of a door and latch, the keeper being shown in connection with the latch;

Fig. 3 is a perspective View of the latch but not showing the keeper.

Referring to the drawings A designates the sliding door to which my improved latch is to be applied, and 10 designates a plate forming part of the latching mechanism, this plate being of sheet metal and being applied to one face of the door A. At its forward edge the plate is slitted at three points so as to form three cars 11, 12 and 13. The ears 11 and 12 are turned in one direcion and the ear 13 in an opposite direction. This ear 13 is formed with a slot 1 1. Pivoted to the plate 10 upon the outside face thereof, is a latch member 16 formed of a strip of metal cut away adjacent its forward end to provide a neck 17 having a rectangular head 18, this head being preferably bent at right angles. The inner edge of the head is disposed slightly beyond the outer face of the lug 13 and this latch 16 is so disposed that the head drops down over the lug 13.

Mounted upon the wall towards which the door is closed as, for instance, upon an upright B. is the keeper 19 formed of a strip of metal angularly bent at its rear end, as at 20, the forward end'of the strip being formed to provide a barbed head 21 with a relatively narrow neck 22 behind the barbed head. This head is adapted to be passed through the slot 14.

lVhen the door is shifted to its closed position, the lug 13 passes over the keeper 19 and the inclined edge of the keeper lifts the head of the latch 16 and then the head of the latch drops down behind the upwardly projecting barb 23 of the keeper, thus latching the door closed. If it be desired to release the door, the latch may be raised from either side, either lifting the head of the latch or depressing the rear end of the latch. The plate 10 is formed with two apertures 2 one at the upper portion of the plate and one at the lower portion of the plate, each of these apertures being for the passage of the rivet or bolt 16' which supports the latch 16. This permits the latch 16 to be changed from the upper hole to the lower hole and from one side of the plate 10 to the other so that the latch will fit on a door that rolls in the opposite direction from the door shown in Figure 1. This I regard as a very important feature of this device as it permits the latch to be applied in different situations.

I claim A latch for sliding doors comprising a plate provided at one end edge with lugs disposed at right angles beyond opposite side surfaces of the plate, one of the lugs being located upon the median longitudinal dimension of the plate and having an opening, the plate being provided with pivot points located at equal distances beyond its median longitudinal dimension, a latch member adapted to be connected with the plate at one of the pivot points and being transversely reduced in the vicinity of one end forming a neck portion which lies substantially at the end of said plate, said latch member having an angularly disposed head portion lying beyond the end of said plate and a keeper body having angularly disposed end portions, one of which is formed in the shape of a barb adapted to pass through the opening of said lug and the said barb having shoulders adapted to engage against the head of the latch member.

In testimony whereof I hereunto aflix my signature.

HARRY E. HUYOK.
